Answer:
The proportion of a genotype (i.e., AB) in a population.
Explanation:
- Every trait is controlled by some alleles and their combinations. Allele frequency determines the frequency of occurrence of a particular allele in a population.
- It can be determined by genotype frequency or proportion of a particular genotype in a population. As a genotype is a result of various alleles coming together, its frequency can help us to calculate the allele frequency.
- For example, in a population with two alleles A and B, A allele can either occur as AA or as AB. To calculate the frequency of A we will have to calculate the genotype frequencies of AA and AB.
